MILSIM Heavy Reserve Bio Airsoft BBs

These 0.40g BBs are specifically engineered for high-power platforms, such as sniper rifles or upgraded DMRs. Standard AEGs typically lack the muzzle energy required to effectively hop or propel a round of this weight, which may result in poor range and velocity.

No, these BBs are designed to remain stable under normal storage and usage conditions. They are engineered to degrade only when exposed to the specific environmental elements found in outdoor soil and water over an extended period.

The 5.95mm sizing is a precision tolerance that minimizes the gap between the BB and the inner barrel wall. This tighter fit reduces air leakage and barrel friction, which helps prevent jams and improves overall shot-to-shot consistency.

Yes, the crisp white color provides high contrast against most outdoor backgrounds, making it easier to track your flight path and adjust your aim accordingly.

The bag is designed for convenience and short-term transport, but for long-term storage, we recommend keeping the BBs in a cool, dry place away from direct sunlight to maintain their structural integrity and biodegradable properties.
